This study builds on the Taylor and Brown theory of positive illusions to attain a more in-depth understanding of the relative influence of perceptual congruence and enhanced perception (positive illusions) on relational satisfaction. A sample of 812, organized into 406 subject-partner pairs of 203 married couples, 100 dating couples, and 103 same-sex roommate dyads completed questionnaires. Each subject rated him- or her-self on six personal qualities (social skills, emotional stability, agreeableness, hostility, depression, and spirituality) and four temperaments (Dominance, Influence, Supportiveness, Conscientiousness). Then they took tests that measured the same qualities to compare with the self-ratings. On another questionnaire, each partner rated the subject on the same 10 qualities. Both subjects and partners completed the Dyadic Adjustment Scale as the measure of relational satisfaction. Primary findings discovered that in most cases, positive illusions diminish relational satisfaction. The only setting in which benefit occurs is when partners rate subjects higher than subjects rate themselves. Congruence between ratings (whether subject-test, partner-test or subject-partner) is strongly associated with relational success. Findings contrast with the Taylor and Brown theory and provide a more nuanced look at the influence of enhancement or congruence.
